      <p><font face="Arial, Helvetica, sans-serif" size="2"><a href="http://www.heros-inc.org/star.htm">Tennessee's 
        Student Teacher Achievement Ratio (STAR)</a> project was a large-scale, 
        four-year, experimental study of reduced class size, that Donald Orlich 
        of Washington State University described in <a href="http://www.pdkintl.org/kappan.htm">Phi 
        Delta Kappan</a> (April, 1991) as "one of the most significant studies 
        in education during the past 25 years."</font></p>
      <p><font face="Arial, Helvetica, sans-serif" size="2"><b>Overview Of The Data Files </b></font></p>
      <p>The
STAR-and-Beyond database contains raw student- and school-level data
from a longitudinal experiment conducted in Tennessee beginning in
1985. The experiment lasted for four years, with a single cohort of
students progressing from kindergarten through third grade. Achievement
tests and non-achievement measures were administered annually. The
experiment ended in 1989. However, student achievement data continued
to be collected through high school, and ancillary studies resulted in
other non-achievement variables being added to the data set. </p>
      <p>The
primary student-level data file contains information on 11,601 students
who participated in the experimental phase for at least one year.
Information for each of grades K-3 includes:</p>
      <p>�	Demographic variables;<br>
      	�	School and class identifiers;<br>
      	�	School and teacher information;<br>
      	�	Experimental condition (�class type�);<br>
      	�	Norm-referenced and criterion-referenced achievement test scores;<br>
      	�	Motivation and self-concept scores.</p>
      <p>Additional data, added to the records of some or all students, include:</p>
      <p>�
Achievement test scores for the students when they were in grades 4 �
8, obtained from the Tennessee State Department of Education;<br>
      	�	Teachers� ratings of student behavior in grades 4 and 8;<br>
      	�	Students� self-reports of school engagement and peer effects in grade 8;<br>
      	�	Course taking in mathematics, science, and foreign language in high school, obtained from student transcripts;<br>
      	�	SAT/ACT participation and scores, obtained from ACT, Inc. and from Educational Testing Service;<br>
      	�	Graduation/dropout information, obtained from high school transcripts and the Tennessee State Department of Education.</p>
      <p>Other data files include:</p>
      <p>(1)
Student data on 1780 students in grades 1 � 3 in 21 comparison schools,
matched with STAR schools but not participating in the experiment;<br>
      	(2)	A school-level file with additional information about each of the 80 STAR schools; <br>
      	(3)	A school-level file with additional information about each high school attended by STAR students. <br>
